Load a Google Map into Unity3D

    Getting Started
    ---------------
    1. Assign the GoogleMap component to your game object.

    2. Setup the parameters in the inspector.

    2.1 If you want to control the center point and zoom level, make sure that
 
       the Auto Locate Center box is unchecked. Otherwise the center point is
 
       calculated using Markers and Path parameters.

    3. Each location field can be an address or longitude / latitude.

    4. The markers add pins onto the map, with a single letter label. This label

       will only display on mid size markers.

    5. The paths add straight lines on the map, between a set of locations.

    6. For in depth information on how the GoogleMap component uses the Google
    Maps API, see: 
    https://developers.google.com/maps/documentation/staticmaps/#quick_example

this is not working

renderer.material is not work.
need change to GetComponent().material

Aww... It really WORKSS!!!!

Thank u so much! ^_^/

@keyserjaya could you share a simple project copy with Load a Google Map into Unity3D, Google Map assets is not longer available in the store, and I'm learning about this, please.

Hi ! I'm also interested by getting a working sample project with the Google Map asset (not longer available on the store) :) Thx !

You can load a map on a plane with this script itself as i got it worked and there is no need of any Map asset.
Things you should keep in mind:

1. Assign this script to a 3d game object like plane.
2. (Very important) You need to get an API key for static maps to get this work.
   Go to the following link and click on "GetStarted" and follow the procedures according to new pricing plans(which sucks) to get an API key.

Hey! I needed this, so I decided to integrate it. You can download a working copy with the updated functions here

Hey! Great work that saved me alot of trouble. Can you please help me load the map as i continue to swipe the screen and it keeps on loading next chunk of map. Any help will really be appreciated.

Hi! i used your source code to show map on an image can you help me with loading a map as i swipe the screen and it loads its next chunk of the map i would really appreciate this
